There is no compound as SO. SO2 and SO3 are acidic
Its name is "sulphurous acid". So it is quite obviously an acid, not a base!
yes it is a base
Li3PO4 is neither an acid nor a base. It is a salt formed from the reaction between lithium hydroxide (a base) and phosphoric acid (an acid), so Li3PO4 is considered to be neutral.
CS2 is a polar covalent molecule that does not ionize in water, so it is not an acid or a base.
An acid or base is never a single element, it is a solution, and a solution that contains H+ OR OH- in it, so oxygen is neither an acid nor base.
Buffers contain both one weak acid and its coupled weak base, that can not react with each other (they are a so-called conjugated system). When you add strong acid it will react with the base part of this buffer, when strong base (hydroxide) is added it will react with the acid.
a base is represented by OH- and an acid is H+ and so when these two are mixed you get H2O so water and salts sometimes
Vinegar is dilute acetic acid, which is an acid, not a base.
NaCl is a salt formed by combination of a strong acid and a strong base, so it can't be put in simple acid or base category.
Carbon trioxide is an unstable oxide of carbon, and is in the form of gas. so no co3 is not an acid
Probably based on vinegar which is acetic acid. So, an acid.
If acid is strong then its conjugate base must be weak, if conjugate base is strong it again accept the H+ ions so acid can neither be strong, similarly if base is strong its conjugate acid must be weak.
